Homework Statement



Hello all, there has been some debate in my class as to the output waveform for the following circuit:
Circuit schematic of a 1 uF capacitor C1 in series with resistor R1 of 1k across a 10V source Vs1, with the input square wave between +10V and -10V and the output waveform shown below it.


Others say that the output will always be zero.
 
I forgot to say that I am really looking for someone to say whether the output in the graph is right, or if it would indeed be zero.
 
The output won't be always zero. How closely the output resembles what you've drawn will depend upon the frequency with which the input signal alternates from + to - and back, compared to the circuit's RC time constant.
 
The other individuals argued that since the ground is connected near the bottom of the resistor, the output voltage, which is in the far right corner, would always be zero.

That's not an argument, it's an unfounded assertion :smile:
